[0016] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0017] Reference Figures 1 to 5The present invention discloses a double-layer circulating pipe conveying device, including mounting frames 10 located on left and right sides, an upper conveying unit arranged at an upper position between the two mounting frames 10, a lower conveying unit arranged at a lower position between the two mounting frames 10, a lifting unit arranged at a lower position between the two mounting frames 10, a descending unit arranged at an upper position between the two mounting frames 10, a driving unit arranged outside the mounting frames 10, and a controller arranged outside the mounting frames 10.

[0019] The lower conveying unit includes a plurality of first rotating shafts 11 and a plurality of transmission plates 12. Each of the first rotating shafts 11 is at the same height and is arranged in parallel at equal intervals. One end of the rotating shaft rotates passively and the other end serves as a power input end. The transmission plate 12 is based on a circular sheet body and has a notch 13 on the side. One side of the notch 13 forms an acute angle with the edge of the circular sheet body and the other side is smoothly connected to the edge of the circular sheet body. At this time, the transmission plate 12 is an asymmetric structure and can be limited in direction. Two transmission plates 12 are installed on one of the first rotating shafts 11. The directions of the transmission plates 12 are the same. The transmission plates 12 on the upper layer and the transmission plates 12 on the lower layer face in opposite directions to realize feeding in different directions. Since the transmission plate 12 will rotate, the direction of its notch 13 will also change continuously. The direction mentioned here does not strictly represent the opposite direction of installation. Figure 2-Figure 4 As can be seen in FIG. 1 , the upper conveying unit conveys material 40 to the right, and the lower conveying unit conveys material 40 to the left. Figure 3 and 4 As shown, the transmission plates 12 in the same layer are arranged in parallel.

[0020] The lifting unit includes a second rotating shaft 21 and a pair of second brackets 22 installed on the second rotating shaft 21. In an initial state, the inner side of the second bracket 22 close to the lower conveying unit is higher than the outer side away from the lower conveying unit. A raised hook is arranged on the outer side of the second bracket 22. The inner side of the second bracket 22 is used to receive the material 40 of the lower conveying unit. The outer side of the second bracket 22 can swing to the top of the upper conveying unit and then transfer the material 40.

[0021] The descending unit includes a third rotating shaft 31 and a pair of third brackets 32 installed on the third rotating shaft 31. In an initial state, the inner side of the third bracket 32 ​​close to the upper conveying unit is higher than the outer side away from the upper conveying unit. A raised hook is arranged on the outer side of the third bracket 32. The inner side of the third bracket 32 ​​is used to receive the material 40 of the upper conveying unit. The inner side of the third bracket 32 ​​can be swung to the top of the lower conveying unit and then transfer the material 40.

[0022] The output end of the driving unit is connected to the input ends of the upper conveying unit, the lower conveying unit, the lifting unit and the lowering unit. Gears are arranged on the same side of each of the first rotating shafts 11 of the upper conveying unit and the lower conveying unit, and the driving unit drives the first rotating shafts 11 of the upper and lower layers to rotate respectively through two different transmission rods or two different conveyor belts, and gears are arranged on the same side of the second rotating shaft 21 and the third rotating shaft 31, and the driving unit drives the second rotating shaft 21 and the third rotating shaft 31 to rotate respectively through two servo motors.

[0023] In this embodiment, the curvature of the notch 13 on the transmission plate 12 is equal to the curvature of the tubular material 40 to be conveyed, and the curvature of the hook on the second bracket 22 and the curvature of the hook on the third bracket 32 ​​are both equal to the curvature of the tubular material 40 to be conveyed, which facilitates the clamping of the material 40.

[0024] Specific reference Figure 5 The dotted line in the figure is only used as a reference circle to assist in indicating the structure of the transmission plate 12. Preferably, the central angle corresponding to the left and right widths of the notch 13 is 50-80°, so as to provide a sufficient gradient length to allow the material 40 to roll stably.

[0025] The operation process of the device is as follows.

[0026] During loading: place the material 40 on the lifting unit, the outer side of the second bracket 22 swings upward to transfer the material 40 to the upper conveying unit, place the material 40 on the lowering unit, and the inner side of the third bracket 32 ​​swings downward to transfer the material 40 to the lower conveying unit. The material 40 falls into the notch 13 of the transmission plate 12, and the transmission plate 12 swings along the notch 13 at a certain angle to push the material 40 to the groove between the two transmission plates 12. The transmission plate 12 of the next level swings along the notch 13 at a certain angle to re-insert the material 40 into the notch 13 ( Figure 4In the embodiment, each transmission piece 12 of the upper conveying unit swings counterclockwise by 10° to insert the material 40 into the notch 13; correspondingly, when the transmission piece 12 swings, the material 40 rotates clockwise in situ), and then swings along the notch 13 by a certain angle to push the material 40 to the groove between the two transmission pieces 12 of the next level, and repeats the above steps to complete the loading. In other embodiments, only the lifting unit or the lowering unit can be used to load the material into the device.

[0027] During operation: the transmission plate 12 of the upper conveying unit reciprocates and repeatedly swings to transfer the material 40 in one direction, and the material 40 at the discharge end of the upper conveying unit finally falls into the third bracket 32, and the third bracket 32 ​​is tilted to discharge the material 40 to the entrance end of the lower conveying unit. At the same time, the transmission plate 12 of the lower conveying unit reciprocates and repeatedly swings to transfer the material 40 in one direction, and the material 40 at the discharge end of the lower conveying unit finally falls into the second bracket 22, and the second bracket 22 is tilted to transfer the material 40 to the entrance end of the upper conveying unit.

[0028] During unloading: the upper conveying unit and the lower conveying unit continue to discharge materials, the lifting unit and the descending unit are open to the outside, and when the material 40 falls into the lifting unit and the descending unit, the material 40 is directly taken away; the matching manipulator is preferably used to form a complete system with the device. In other embodiments, the material 40 can also be taken away only from the lifting unit or the descending unit.

[0029] Of course, when the device is used in practice, it is also necessary to arrange a housing, a number of heaters and a number of spray units, and the above components can be purchased on the market and used directly.
